"Today, with properly organized tool rooms, accurate tool measuring equipment and profile grinding techniques, changing molding patterns within two or three minutes is well within the realm of possibility," says Bob Metz, product manager for SCM's moulder division.
One way moulder productivity is increasing is advances in the tool room, including axial constant grinding.Axial constant grinding of the cutter heads uses a series of reference points so that when you grind the knives in the tool room and transfer the cutter head to the spindle in the moulder, the reference points remain the same.

"With SCM's system, you just have to measure the tool diameter and dial that in to the digital counter, enter in the thickness of the finished product and you're finished," says Metz.
Spindle design has also improved to allow feed speeds of 8,000 to 12,000 rpm (rather than the traditional 6,000 rpm) on some models when equipped with the proper tooling.The higher spindle speeds allow between 30 percent to 40 percent faster feed speeds without the need for jointing technology.
Advances in moulder design aren't limited to the flagships of manufacturers' lineups.Smaller moulders have benefited from a trickle-down of technology, as many of these improvements are found as standard or optional on most machines.
